Mycorrhizae are fungi who have formed a symbiotic relationship with the majority of
terrestrial plants early in plant evolution. The extensive, interconnected network of fungal
hyphae extends from within the root tissue of its' host root tissue and out into the soil.
These hyphae help the plants in numerous ways:
Hyphae explore the soil for nutrients & water, transport them back to the plant, and help
bind soil particles into aggregates
In phosphorous deficient soil, mycorrhizae transport enough phosphorous to result in
10-20 x increase in growth. Where there is an abundance of phosphorous, little difference is
growth exists.
Reduction of weedy competition: Weeds tend to require more available nutrients in the soil
than perennial natives, and the fact that mycorrhizal hyphae and roots remove them quickly
is a key factor in suppression of weed growth by healthy native vegetation.
Some of the mycorrhiza of the plant family Ericaceae only appear to significantly improve
the uptake of nitrogen, and ectomycorrhiza may do the same in some conditions.
In other species associations, the hyphae can pick up micronutrients such as copper or zinc.
The hyphae of AM fungi can make up to 70% of the soil's microbial biomass which results
in the binding of soil particles.
It is common for most of the plant species in an ecosystem to be interconnected below
ground by their mycorrhizal fungi. Thus this network may regulate transport of sugars
as well as disease vectors between plants of the same and differing species The extent
of lateral transport is still being studied.
Some studies indicate that mycorrhizae may help plants resist attack by other microbes.
